The book "Inside the TRS-80 Model 100" is $19.95 from Weber Systems, Inc. 8437 Mayfield Road, Chesterland, Ohio 44026. This is definately the book to get if you are interested in programming the 100. Although it does not include a disassembly of the ROM, it does include all the published entrypoints and many more unpublished entrypoints. Did you know it is possible to make a Model 100 talk? If you digitize an audio sample on another machine and convert the wavefrom to a time-until-zero crossing format, do an appropriate timing loop in the Model 100, and then toggle the piezo-electric buzzer, you'll get low-res, but recognizable speech. I've heard the same trick done on an apple ii, and an IBM PC has equivalent hardware. This book gives you the calls to get at the piezo buzzer. (My current project is turning the 100 into a traveling musician's notepad for my wife, a professional musician.) > The mac is a detour in the inevitable march of mediocre computers. > drs@bnlux0.bnl.gov (David R.
